How do I change the screen size on my computer game?

I have a laptop and I'm trying to play the game the Crystal Key v. 11, it runs well, I just want the screen to be bigger, its only in the middle of the screen. My laptop is a Microsoft Windows XP Home Edition, Service Pack 4. I have an Intel(R) Pentium (R) M processor. I really need some help, please. Thanks!How do I change the screen size on my computer game?
Click 'tools'. Click 'full screen'. OR click 'page'. Click 'zoom'. Or hold down 'ctrl' key, rotate wheel on mouse. up for larger, down for smaller.How do I change the screen size on my computer game?
Try pushing F11. It usually brings it up to be full screen, and if you push it again, it'll be regular again.
I play the sims 2, and that happened to me. I went into settings on my game while I was playing and clicked on screen size. There I could change from 800 x 600, and things like that. I hope it helps a little.
well first you got to circumnavigate your debuff and create a new field with your fusion 2000. open the e.v.e folder and select traymanager.exe. then use the ADSL option to clear out the traymanager.exe. You then, finnally have to debug the computerized micr55'9. There you go, problem solved.
I think its nothing to do with laptop setting, all you need to change your game set up, look at help in game and change the screen size from game settings.
